:mod:`json` -- JSON encoding and decoding
=========================================
.. module:: json
:synopsis: JSON encoding and decoding
|see_cpython_module| :mod:`python:json`.
This modules allows to convert between Python objects and the JSON
data format.
Functions
---------
.. function:: dump(obj, stream, separators=None)
Serialise *obj* to a JSON string, writing it to the given *stream*.
If specified, separators should be an ``(item_separator, key_separator)``
tuple. The default is ``(', ', ': ')``. To get the most compact JSON
representation, you should specify ``(',', ':')`` to eliminate whitespace.
.. function:: dumps(obj, separators=None)
Return *obj* represented as a JSON string.
The arguments have the same meaning as in `dump`.
.. function:: load(stream)
Parse the given *stream*, interpreting it as a JSON string and
deserialising the data to a Python object. The resulting object is
returned.
Parsing continues until end-of-file is encountered.
A :exc:`ValueError` is raised if the data in *stream* is not correctly formed.
.. function:: loads(str)
Parse the JSON *str* and return an object. Raises :exc:`ValueError` if the
string is not correctly formed.
